Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[Middle English, from Old French, from Latin mūsculus, diminutive of mūs, mouse; see mūs- in Indo-European roots.]

from Wiktionary, Creative Commons Attribution/Share-Alike License

From French muscle, from Latin mūsculus ("a muscle", literally "little mouse"), because of the mouselike appearance of some muscles, from Ancient Greek μῦς (mus, "mouse, muscle, mussel"). Cognate with Old English mūs ("mouse", also "muscle"). More at mouse.

  • "Muscle" stems from the word mouse. People believed watching muscles move looked like a mouse crawling under the skin.

  • Latin musculus is a homonym meaning both muscle and a small mouse. The same semantics are found in Greek pontiki. But the Greek mouse was derived from "mus Ponticus", mouse from the Pontus region, where Pontus was the biceps on a male anthropomorphic map. The etymology of muscle is unrelated to mouse. It is related to concepts such as weight, mass, and massage. It is probably related to Semitic mem-sin-aleph, lifting up, burden, load at a time when the aleph still had a chs-sound, and to mem-shin-kuf-lamed MiSHKaL weight. If you lift weights, you will develop your muscles. If you have a lot of muscle, you can lift / carry / pull a lot of weight.

  • There is a similar correspondance in the Slavic languages between muscles and mice, e.g. Russian мышца (myshtsa, "muscle") / мышь (mysh', "mouse"); and Slovene mišica ("muscle") / miš ("mouse"), where the suffixes -tsa, -ica form diminutives.
